We present time and range distributions and histograms of the parameters and cross-correlations among them. With K index at Syowa Station the distributions and histograms vary slightly but the correlations do not change so much. The most noticeable feature is that there is a positive correlation between the absolute values of Doppler velocity and echo power. This relationship can be interpreted in terms of the gradient-drift instability which is the most probable cause to generate decameter-scale irregularities in the F-region ionosphere.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006276","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11397422","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Solar-Terrestrial Environment Laboratory, Nagoya University/Solar-Terrestrial Environment Laboratory, Nagoya University/Solar-Terrestrial Environment Laboratory, Nagoya University/National Institute of Polar Research/National Institute of Polar Research/ National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1999-09-01"}],"displaytype":"detail","filename":"KJ00000048016.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048016","url":"https://nipr.repo.nii.ac.jp/record/6276/files/KJ00000048016.pdf"},"version_id":"ee37cdc4-4e52-4785-9d0e-86c638fb4fe0"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Statistical analysis of echo power, Doppler velocity and spectral width obtained with the Syowa South HF radar","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Statistical analysis of echo power, Doppler velocity and spectral width obtained with the Syowa South HF radar"}]},"item_type_id":"1","owner":"4","path":["803"],"pubdate":{"attribute_name":"公開日","attribute_value":"1999-09-01"},"publish_date":"1999-09-01","publish_status":"0","recid":"6276","relation_version_is_last":true,"title":["Statistical analysis of echo power, Doppler velocity and spectral width obtained with the Syowa South HF radar"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:40.941249+00:00"}
